How we worked it out

Updated as you change the numbers.

  1. GDP = C + I + G + (X − M). Real growth = (1 + nominal growth) ÷ (1 + inflation) − 1.

Method and assumptions

The expenditure approach adds up final spending in the economy: household consumption, business investment, government purchases and net exports. Imports are subtracted because they are counted in the other parts but produced elsewhere.

Questions

Why are imports subtracted from GDP?

Spending on imports is already included in consumption and investment, but GDP measures only what is produced at home.
